Pour the pineapple juice, mango (or passion fruit) juice, and lemonade into a large pitcher. Give it a slow swirl just to wake everything up. The juice combo should already smell like vacation.

Pour in the coconut rum. This is what gives the drink its smooth island flavor — a soft coconut sweetness that blends beautifully with pineapple and citrus.

This is the magic moment. As soon as the blue curaçao hits the pitcher, the whole mixture turns into a gorgeous shade of deep ocean blue. Don’t rush this step — watching it swirl into the juice is honestly therapeutic.

Fill the pitcher at least halfway with ice. I like adding extra because as the ice melts, it cools and slightly softens the sweetness.

Right before serving, pour in the lemon-lime soda to give it that refreshing, fizzy finish. This makes the drink lively and light.

Give everything a slow, gentle stir. Not too much — you don’t want to destroy the carbonation. Add garnishes like lime slices or pineapple wedges if you want that “tropical bar” vibe.

Pour into tall chilled glasses, add more ice if needed, and enjoy your island escape in a cup.
